Here is a Kochs Beer Ball Knob from the Koch’s Inc. Brewery located in Williamsport, PA. This Kochs Beer Ball Knob is from 1936 and is in excellent condition for it’s age.
This Kochs Beer Knob is made of black glass with enamel lettering. Knobs like this one were made by the J. E. Newman Company located in Pittsburgh, PA. The glass beer knobs were only produced for a short time then replaced with aluminum knobs as the glass knob design were too fragile during use and over time.
